There's only three mugo guys, the one in the red pane is the monster mugo we see on the last panel, he's the one who eats the scarifices. What I'm curious about is those white things, my theory is that they are the souls of the sacrifices in the past.
I don't think so. I think the shadow figure with white eyes is the 4th one that eats the sacrifices. Monster Mugo showing up at the end is to throw the readers off imo.
